Brassinolide-induced elongation

Physiologia Plantarum, 1992
The promotive effects of brassinosteroids (BRs) on elongation seem general, as members of the family affect young vegetative tissue in fifteen species (listed in Sasse, 1991a). There is also a specific effect, as 24-epibrassinolide (24epiBL) forms part of the sequential response in young elongating tissue (Sasse, 1985). The case for BRs as a new family

Stereocontrolled synthesis of the brassinolide side-chain: formal synthesis of brassinolide

Journal of the Chemical Society, Perkin Transactions 1, 1988
The stereoselective introduction of the brassinolide side-chain, having a (20S,22R,23R,24S)-22,23-diol functionality, was examined. The catalytic reduction of (20S,22R,24Z)-6β-methoxy-23-oxo-3α,5-cyclo-5α-stigmast-24(28)-eno-29,22-lactone (11), derived from the 20-carbaldehyde (7) and 3-isopropyl-2-lithiofuran in three steps, afforded (20S,22R,23R,24S)-

Improved synthesis of brassinolide

Journal of the Chemical Society, Perkin Transactions 1, 1996
Brassinolide has been synthesized from stigmasterol in an overall yield of 7%. The key step in the synthesis is aldol condensation of 2α,3α-isopropylidenedioxy-6-oxo-23,24-dinor-5α-cholan-22-al with 3-isopropylbut-2-enolide carried out at – 78 °C, which gives a product with 22R,23R stereochemistry in high yield.

Brassinolide analogues without side chain

Collection of Czechoslovak Chemical Communications, 1989
New brassinolide analogues, characterized by a modified androstane structure without substituent in position 17, were prepared. In the second internode assay, 2α,3α-dihydroxy-B-homo-6-oxa-5α-androstan-7-one (XVII) had the highest brassinoid activity.
